IMPROVED BOLT-CUTTER.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, W. W. WORDEN, of the town of Waukesha, county ofWaukesha, and State of Wisconsin, have invented a new and usefulImprovement in Bolt-Trimmers; and I do hereby declare that the followingis a full, clear, and exact description thereof, which will enable thoseskilled in the art to makeand use the same, reference being had to theaccompanying'drawing, forming part of this specification, in which-Figure 1 is a side view of the trimmer.

Figure 2, a. bottom view.

Figure 3, eccentric lever, cutting-knife, anti-friction roller, andconnecting-link.

Figure 4, connecting-link. v

Figure 5, top view of cutting-knife in place.

Similar letters of reference in each of the figures indicatecorresponding parts.

The object of my invention is to provide a tool for trimming the ends ofbolts that project above the nuts after the nuts are set up firmly inplace.

A is the bed-piece; B, an eccentric-lover, which operates thecutting-knife; C, the cutting-knife; D, a

roller in the back end or butt of the cutting-knife, to lessen thefriction of the eccentric-lever when operating the knife; E, hook whichconnects the cutting-knife and eccentric-lever; it hooks into one end ofthe roller D, and into a. hole in the lever. This hook draws the knifeback when lever B is raised. The roller D is embedded in the butt of thecutting-knife more than half its size, and is put in place and taken outby shoving it endwise. F is a slot in the side of the eccentric-leverfor the hook E to work in. It is just deep enough to let the hook E comeflush with the side of the lever, and when the lever is in place theside of the bed-piece A. keeps the hook from working out. G is a pin,making a fulcrum for lever B; H, pin through bed-piece A, under which.knife C works; I, a piece of steel, dove-tailed into the bottom ofbed-piece A for the nut to rest against when the bolt is being trimmed.I

Operation: .Place the timmer over the end of the bolt and nut, raisinglever B to draw the knife back, the nut entering the square hole inbed-piece A till the knife rests on it, the point of the bolt projectingabove the nut and above the edge of the knife. Lever B is then broughtdown, which forces the knife forward, its edge striking the bolt closedown to the nut. The nut is forced against the steel bar I, which ismade bevelling on the upper side, which prevents the nut from slippingshould it be tapering, and as the knife is thus thrown forward, the boltis trimmed off close down to the nut. l

What I claim as my invention, and desire to secure by Letters Patent,is-

Eccentric-lever B, hook E, roller D, and cutting-knife C, incombination, substantially as described.
